Add a cast in case the caller passes in a different type, as it would if mtspr/mtmsr were functions. Previously, if a 64-bit type was passed in on 32-bit, GCC would bind the constraint to a pair of registers, and would substitute the first register in the pair in the asm code. This corresponds to the upper half of the 64-bit register, which is generally not the desired behavior. Signed-off-by:
